In early organic-chemistry publications, where use of graphics was strongly
limited, a typographic system arose to describe organic structures in a line of text.
Although this system tends to be problematic in application to cyclic compounds,
it remains a convenient way to represent simple ...

Complete structural formulas show all the atoms in a molecule, the types of
bonds connecting them, and how they are connected with each other. For a
simple molecule like water, H2O, the molecular formula, becomes H-O-H, the
structural formula. This structural formula shows that in a water molecule, the
oxygen atom is ...

A structural formula is a chemical formula that gives you a more complete picture
of a compound than its molecular formula can. While a molecular formula, such
as H2O, shows the types of atoms in a substance and the number of each kind of
atom, a structural formula also gives information about how the atoms are ...

Condensed Structural Formulas. Although structural formulas have the
tremendous value of showing which atoms are bonded to which other atoms,
they do have a few drawbacks. One is that they are two-dimensional and the
molecules they represent are three-dimensional. I have already mentioned that
we need to use ...

Condensed structural formula: The condensed structural formula still uses lines
between bonded atoms, but is an easier and shorter way to draw the line-bond
structural formula because it omits the carbon and hydrogen bonds. We can see
this when we compare the line-bond structural formula with the condensed ...

Let's say we're given the molecular formula C three H eight O, and we're asked to
draw a Lewis dot structure. So on the left here is one possible Lewis dot structure
that you can draw that has that molecular formula. There are three carbons, one,
two, three. There's one oxygen, right here. And if you count up the hydrogens ...

figure. This representation is called a structural formula, in which lines depict two
electron bonds between atoms. Look at the propane structure and observe that
the four bonds to each carbon complete its valence orbitals with eight electrons.
In the diagram of propane, the most important feature is the chain of three
carbons.
